## Description

desertcart.com : EF-EOS M2 Autofocus Lens Adapter 0,71x Speed-Booster Compatible for Canon EF Lens to EOS-M Mount Camera CAN0N EOS M M2 M3 M5 M6 M10 M50 M100 M200 : Electronics

Review: Plug and play - Works perfectly. I got it so I can use a Canon EF 70-300mm f/4-5.6 IS USM lens on my Canon EOS M50 Mark II.
Review: Fast and awesome - I guess I got lucky because my copy’s AF is fast. I tried it on my Nikkor 50mm 1.8 and sigma 18-35mm 1.8 AF was fast and focus is spot on. The fitment is nice and tight, it’s not loose at all. The only con is that the AF doesn’t work on 4k 24fps but it does work on 4k 30fps video. Awesome and a must have if you have tons of nikkor lens or f mount lens that you want to use n your M43 camera body.

## Features

- Compatibility: EF-EOS M2 metal lens converter compatibly connect CAN0N EF series lenses to EOS M mount cameras (EF-M mount), including CAN0N EOS M M2 M3 M5 M6 M10 M50 M100 M200.

- Quick and precise AF (auto-focusing); support aperture adjustment; parameters of aperture, shutter speed, exposure and ISO can be controlled directly from camera side.
- Inbuilt Micro USB Port: designed with a micro USB port for upgrading new firmware; convenient to get new improved functions, fix bugs and expand compatibility of more related lens and camera.

### ⭐⭐⭐⭐⭐ Works great for both EF and EF-S lens
*by M***B on July 8, 2021*

I probably would have purchased the Canon version for my new R6, however it was unavailable and I needed it sooner. I ordered this one thinking I could always return it if needed. Glad to say that it works great and so will be a keeper. I find it to have a solid feel with all of my glass and hasn't malfunctioned at all. I don't have any RF lens yet so can't compare, but the auto focus is super fast with my Canon 70-200 2.8. When I tried an EF-S lens, it worked fine and the R6 automatically set it to a 1.6 crop.
